Stock style rods, 4.09 bore, nothing heavy
Does one brand internally balance easier (less heavy metal)?
-
I am of zero help on this one - Sorry Ross!
-
Maybe someone whose name rhymes with "Barry" will know LOL
-
I though Scat or Eagle offered a internally balance crank as a option ??
-
I think it says that on the website, but I don't think its true.
I'll tell you, its crazy, got emails out to all the normal guys and can't get a quote back on a crank. Hopefully this week someone will answer
-
I just talked to Eagle.
"Sir, our FE cranks are internally balanced in the front, externally balanced in the rear"
I guess that could be a way to look at it... :o and you wonder why so many people get confused with stuff like this.
-
Being the habitual smartass I am, my next question would have been "Oh, so is it half-internal half-external balanced in the middle?" :P

What a joke! Carroll Shelby is dead, but there's still a bunch of snake oil out there...

Sounds right to me. It's like a 428 crank, only needs rear weight, unlike a small block that needs weight on both ends, or a 390 that needs no weight.
He is letting you know you don't need a front a counter weight but it will need flex plate/flywheel counter weight.
On an aftermarket crank, that is good information to know.
You could just call it externally balanced, but his description is more accurate.

These cranks are externally balanced and use a neutral balanced spacer and balancer like any other non-SCJ 428.
I do not consider his statement more accurate, and when I look at the website, I think they confuse people. I am betting you'll agree when you see the pic below.
I know its semantics, but once a crank needs an offset weight, its an externally balanced rotating assembly.
I know I am preaching to the choir, but SCJs are externally balanced that need weight on both ends, a CJ/PI/410 is externally balanced that needs weight on one end. I understand the Eagle is designed to be the latter
No doubt, saying its internally balanced on one end but not on the other CAN be explained, but it's not correct, nor is that a reason that it cannot be internally balanced like they told me, guys are doing it all the time
I just don't like when terminology is misused, if someone clicked on that website to order one, the site below leads them to believe its internally balanced. See the screen capture below. For them to come back and say that this means its "internal on one end" is ridiculous and a play on words IMHO

I have to agree after seeing their advertisement, that it is very misleading, but you did not post that before.
With only your statement that I quoted to go by I still say what the guy said is more accurate.
Never the less it is bull$hit to advertise that crank as internal balanced.
So I am going to agree with you with the additional information. Very misleading.
-
Thanks, I was posting on both sites so I must have left some details out (sort of like Eagle) LOL
Regardless, I bought an Eagle anyway, we'll soon see how it worked out. Got jobber price locally, double bonus.
-
I have the eagle 4.25 crank and I used a zero balance flywheel. I bought the flywheel from Brent.
-
Did you have the rotating assembly balanced?
-
Yes it was balanced 13lb aluminum flywheel, pressure plate and all. I sold all the SCJ stuff hatchett, flywheel, crank and the rods.

Just getting back from a family vacation...
No info on the Eagle. But we've done a few of the Scat ones. They usually balance internal pretty easy - but often still need weight in the rear. Less than when using a factory crank. Very much determined by the piston & rod selection. The lighter you go the less metal we're adding & we can just drill/grind. With tungsten costing around $60-75 per slug installed this sometimes pays for a piston upgrade...

Barry, looks like a max bobweight of 2100 grams, but I could pull more out of them if I wanted, all the parts have plenty of pad left.
That's lighter than my 489, but do you consider it light or heavy for an internally balanced 3.98?
